Why have a default handler if you have an AUTOLOAD in the
first place? The main use would be something that installs
a newly minted subroutine, e.g.,
sub AUTOLOAD
{
my $name = (split /::/, $AUTOLOAD)[-1];
my obj = $_[0];
my $sth = $dbh->prepare( $obj->{$name} );
my $sub =
sub
{
my $obj = shift;
eval
{
# caller gets back undef (false) on
# failure or the result of the query
# (which may be undef).
$sth->execute( @_ );
$sth->fetchall_arrayref
}
};
# where symbolic ref's Do the Deed (tm).
{
no strict 'refs';
*$AUTOLOAD = $sub;
}
# doublecheck my syntax on this, it may be
# just *AUTOLOAD or require braces -- the
# camel has a working example.
goto &*AUTOLOAD
}
i.e., if the object contains a key with the name of your
called subroutine then treat it as sql, prepare a statement
handle, construct a closure on it, install it as
the subroutine to call that statement handle, then dispatch
to it with the current arguments.
This is how the .al items work; see also the Shell module.
